RFP30P06 Equivalent & Substitute Parts

Part Overview

The RFP30P06 is a P-Channel MOSFET rated for 60V drain-to-source voltage with a continuous drain current of 30A at 25°C. This device is packaged in a Through Hole TO-220-3 configuration and is manufactured by onsemi. The RFP30P06 is classified as obsolete, making identification of equivalent substitute components necessary for ongoing design support and procurement planning. Substitute parts must maintain electrical compatibility across critical parameters including voltage rating, current capacity, and gate characteristics while accommodating packaging and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFP30P06 are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Mandatory Matching Parameters:

• FET Type: P-Channel
• Drain to Source Voltage (Vdss): 60V
• Package / Case: TO-220-3
• Mounting Type: Through Hole

Compatible Parameter Ranges:

• Continuous Drain Current (Id): Equal to or greater than 30A
• Rds On (Max): Equal to or lower than 65 mOhm (lower resistance is acceptable)
• Vgs(th) (Max): Equal to or lower than 4V (lower threshold is acceptable)
• Gate Charge (Qg): Lower values are acceptable for reduced switching losses

The FQP27P06 meets the mandatory matching criteria and operates within compatible electrical ranges. While the FQP27P06 has a rated continuous drain current of 27A (lower than the RFP30P06's 30A), it maintains the same voltage rating, package type, and threshold voltage specification. The FQP27P06 is classified as Active product status with ROHS3 compliance, providing a viable path for designs requiring modern component qualification.

Engineering Selection Recommendations

FQP27P06 as Primary Substitute:

The FQP27P06 is the appropriate substitute for the obsolete RFP30P06 based on the following engineering criteria:

1. Electrical Compatibility: Both devices share identical voltage ratings (60V Vdss) and threshold voltage specifications (4V @ 250µA). The FQP27P06 maintains gate charge and input capacitance characteristics suitable for equivalent switching performance in most applications.

2. Current Rating Consideration: The FQP27P06 is rated for 27A continuous drain current compared to the RFP30P06's 30A. Applications operating at or below 27A continuous current at 25°C are directly compatible. Applications requiring the full 30A rating require thermal and circuit analysis to confirm FQP27P06 suitability.

3. Product Status and Compliance: The FQP27P06 carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The RFP30P06's obsolete status and RoHS non-compliance status make transition to the FQP27P06 necessary for new designs and ongoing procurement.

4. Packaging: Both devices use identical TO-220-3 Through Hole packaging, eliminating mechanical redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the FQP27P06 directly replace the RFP30P06 in all applications?

A: Direct replacement is valid for applications operating at continuous drain currents of 27A or below at 25°C. Applications requiring the full 30A rating must evaluate thermal performance and circuit operating conditions. Both devices share identical voltage ratings, threshold voltages, and packaging, ensuring mechanical and electrical interface compatibility at rated current levels.

Q: What is the significance of the lower gate charge in the FQP27P06?

A: The FQP27P06 exhibits lower gate charge (43 nC @ 10V) compared to the RFP30P06 (170 nC @ 20V). Lower gate charge reduces switching losses and improves switching speed, providing a performance advantage in high-frequency switching applications. This characteristic does not prevent substitution; it represents an improvement in switching efficiency.

Q: Why is the RFP30P06 classified as obsolete?

A: The RFP30P06 is no longer in active production. The FQP27P06, part of onsemi's QFET® series, represents the current-generation equivalent with improved specifications, active product status, and modern compliance certifications including ROHS3.

Q: Are there packaging differences between these devices?

A: Both the RFP30P06 and FQP27P06 use identical TO-220-3 Through Hole packaging. No mechanical redesign or PCB layout modifications are required for substitution.

Q: What compliance differences exist between these parts?

A: The RFP30P06 is RoHS non-compliant, while the FQP27P06 is ROHS3 compliant. Both devices are REACH Unaffected and carry EAR99 ECCN classification. For applications subject to RoHS regulations, the FQP27P06 is the required choice.

Q: How do the Rds On specifications compare?

A: The RFP30P06 specifies 65 mOhm @ 30A, 10V, while the FQP27P06 specifies 70 mOhm @ 13.5A, 10V. These measurements are taken at different current levels, making direct comparison complex. At equivalent gate drive conditions (10V), the FQP27P06 demonstrates comparable on-resistance performance within its rated current range.
